The Redskins enter their final week of the preseason, and I don’t know about you, but I’m ready for the regular season and some meaningful games.

This will be an interesting week because of the roster cuts, and Thursday will give a number of bubble players another chance to fight for jobs. But for the starters, this week is about little beyond staying healthy.

The Redskins will practice today and Tuesday before traveling to Tampa on Wednesday. They’ll play the Bucs on Thursday night, roster cuts will be made by 4 p.m. Saturday, and then the focus will turn to the Sept. 9 regular season opener.

But first, let’s take a dip into the mailbag, where once again, we tackle all things Redskins. Thanks, as always, for sending your questions. And, apologies to anyone whose question didn’t get answered today. Some early-morning roster cuts cut into my time, and now I’m headed to this morning’s open locker room session!

What would happen if Rex Grossman or Pat White were to get injured? It is not uncommon for QB injuries, so is there a back-back up plan? Direct snapping to running back?

– Alex McDonald

Direct snapping the ball to a running back is one option. The Redskins also have a couple of former quarterbacks like wide receiver Josh Morgan and tight end Jordan Reed on the roster. The last couple years, Brandon Banks was the player the Redskins would’ve turned to as the “emergency quarterback.” I haven’t thought to ask Mike Shanahan about this yet, but my guess would be Morgan. I’ll try to find out for sure.

I wanted to ask about how the Lisfranc injuries have started to be more prevalent in the news. Is this a new name for an old injury or, due to the advances in sports medicine, has there been an increase in the detail at which foot injuries can be separated into different types (sprain, break, Lisfranc, bone spurs, etc.)? I just don’t remember ever hearing of a Lisfranc injury until recently.

– Steve Greenfield

Last season seemed to feature a rash of Lisfranc injuries across the NFL with Santonio Holmes, Cedric Benson and Ryan Kalil ranking among the most notable players. But the Lisfranc injury isn’t new. The origin of the name of that joint in the foot actually dates back some 200 years to when Jacques Lisfranc de St. Martin – a surgeon in Napoleon’s army – who detailed the anatomy of the foot. But, anyway, it has been speculated that the number of Lisfranc injuries has risen because of the strain that comes along with athletes now being bigger, and faster and creating more strain as they make cuts or get in pileups.

With injuries and suspensions at defensive end, have the Redskins reached out to Richard Seymour?

– Bryan Sampson

The Redskins have not expressed interest in Seymour, I’m told. They feel good about the depth they have at the left defensive end position with Kedric Golston and Chris Baker holding things down until Jarvis Jenkins returns, and with Adam Carriker out for the season. A 12-year veteran, Seymour doesn’t fit the mold of young, more affordable players that this Redskins regime has pursued.

If Robert Griffin III is ready to go – that is to play full out pre-season and beyond – why is he still wearing the knee brace?

– Morris Peters

Although Griffin believes he is capable of playing right now, Mike Shanahan made it clear he will not see any action until the regular season at the earliest. But, even when he does return to action, Griffin will wear that knee brace as a precaution. It will give him support and extra stability when he makes cuts, and hopefully protection as when tackled. Griffin wore a knee brace his entire junior season at Baylor when he returned from a torn anterior cruciate ligament suffered as a sophomore. Griffin didn’t wear the brace during his senior season at Baylor.

Why is RGlll allowed to get away with so much? His head is too big for his britches, as my grandfather would say. He seems to think he knows more than his coaches and doctors. And, the way he was talking on the air about going into the games and playing, was disrespectful and arrogant. His arrogance in his “apparel” is just another sign of disrespect.

– Anne Marie Martinez

I wouldn’t say he’s gotten away with “so much.” He has drawn criticism from columnists and analysts for his honesty, but really, Griffin didn’t say anything that Mike Shanahan hadn’t already said when he revealed that he didn’t like and didn’t totally understand the coach’s plan for him. Shanahan the week before had said that he didn’t expect Griffin to like every decision he’s made. The Adidas gear, which he has been fined for, has generated controversy, and fines ($20,000 total). It’s hard to say if wearing the “Operation Patience” shirt was him snubbing his nose at the league, or if it was him not realizing that he could still be fined for wearing it during a workout for a game in which he wasn’t even going to play in.

Why did Bruce Allen indicate during a presser that the salary cap [penalty] from two years ago would actually have a negative effect on the Redskins for the next two years? And I thought this would really help us, not restrain the team. Secondly, why did the team’s old special teams coach [Danny Smith] leave the Skins to take the exact position with another team? Did he sense trouble here? That kind of got me worried.

– Olufemi Adepoju

Allen’s argument is that the penalties the past two years set the Redskins’ efforts back in each of the last two seasons, and kept them from rebuilding as quickly as they wanted to, and that by not being able to address some positions the last two years, they have more needs to meet down the road. Possible example, had they been able to spend big and get Cortland Finnegan as they wanted last season, they might not have had to use that second-round pick on David Amerson this year, and could’ve used it on some other area of need. Not sure I totally buy the argument, however. The team is expected to have more than $40 million in cap space next year, so they can spend as freely as they wish. But, just because they have that money doesn’t mean they will use it. The Redskins appear to be doing pretty well despite the cap hits. The cap restrictions have forced the Redskins to build through the draft and with financially-smart free agent signings rather than flashy moves that carry more risk.

[Editor’s note: Allen’s argument also seems to be about the Redskins inability to carry forward whatever unused cap space they would have had over the past two seasons, bolstering future cap space]
